--I Specification of Letters Patent.

Application filed April 4, 1911.

To all whom it may) concern: 1 7

Be it known that I, HENRY W. ZEMKE,

a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented newand useful Improvements in a CombinedSafety Letter-Sheet and Envelop or the like, of which the following is a specification.

- My invention relates to a combined-lettersheet and envelop, that possesses superior advantages with respect to construction and has for its objects to improve and simplify the methods of its use.

' The primary object of my invention is to provide such an article in a more economical mannerthan the method now in use, as to a saving of material and labor, in cutting,

gumming, folding, addressing, sealing and 7 opening. v

A further object of my invention is to provide a combinationform, of the above character, in which matter of any process or description, incl'osures, advertising-pages, etc, may be safely enveloped and transmitted from one party to another with one side or end open for postal inspection, without the aid of extraneous fastening devices and without danger of being moved or lost therefrom.

Another object of my invention is to provide means, whereby the letter-sheet and envelop may be addressed simultaneously, at the time of writing the communication, to avoid the erroneous handling and the frequent mistakes caused by the placing of a letter addressed to one addressed to another; and to provide means to facilitate the removal of the letter-sheet and its inclosures, so that it can be done ef-' fectually and quickly without cutting the side or end edges of the envelop; to avoid the danger of tearing the letter-sheet and the obviously unsatisfactory and inconvenient method wise or blowing into same in order to remove the contents.

With the above and other objects in view that will appearas the description proceeds, the invention consists in the novel construction and arrangements of the parts, that I shall hereinafter fully describe and then point out the novel features thereof in the appended claim.

For a full understanding of my invention 'flaps united. F1g. 4 is a unintentionally reperson in an envelop of squeezing the envelop edgei the back face of section Serial No. 618,906.

and the merits ing drawings in which Patented Feb. so, 1917.

thereof reference is to behad' to the following description and accompanymy invention, showing. the letter-sheet folded, and flaps unfoldedwitha row of perforation and an adhesive coating extended along limited inner surface areas of the combined end andzside flap. Fig. 2 is "a i front face viewof the envelop, and Fig. 3 of same'showing the end perspective view showin-gthe side flap severed and the lettersheet unfolded, opened. 7 a I Similar lettersand figures refer to similar parts throughout the several views.

eferring now more particularly to the after same is sealed and drawings, there is shown a :combination' form of a letter-sheet and envelop, comprising sections 1, 2, 3 and 4, an end flap A, and a combined end and side flap B provided with a row of perforations c, and

ited inner surface areas.

In practice sections 1, 2, 3 and 4, are bent inwardly along line al and then transversely along linea to the back face of section 3, thus retainingvan inclosure' which may be placed between the inner faces of sections 1 and 3, or sections 2 and 4. Thereafter the combined end and side flapBhand B is bent along line (i and folded inwardly over the outer free side edges of said folded sec tions; so as to permanently unite the inner faces of end flaps A and B, with each other, after which the said endflaps may be bent transversely along line a as shown in Fig. 3-, thus forming an envelop to safely protect the contents yet having one side and end open to simultaneously extract or inclose the letter-sheet and an in'closure. By this folded arrangement the fold lines are dented and 1, is exposed to receive an address and a postage stamp.

In postal practice, the sealed end flaps A and B, and outer exposed folded ends of sections 2 and 4, may be gripped and either bent or .pulled' outward so as to expose the loose edges of said sections, in order to examine the'contents and to unfold the lettersheet; however, the corners opposite the diagonal'edge of said side flap B may he gripped and bent similar, in order to obtain an adhesive coating 6', extended along 'limequivalent results. The recipient may do likewise or tear off sealed end flaps A and B, along their dented edges.

When the invention is intended to be transmitted sealed, it is made up and operated comparatively the same as first described above with the exception that the inner face of side flap B is then united with the back face of section 2, and that the said side flap B will tear along the row of perforation 0, when extracting the letter sheet, and appear as shown in Fin. l.

,Further when the said letter-sheet and envelop is addressed simultaneously, sections 1, 2, 3 and i, are folded alongline a to the back faces of each other, the address ing being done in this instance on the front face of section 3, of the letter-sheet, and transferred to the back face of section 1, of theenvelop with theaid of a carbon paper, between the back faces of sections 1 and 3, at" the time of writing the communication, with the full address of the party, that is, date, name, number, street, etc, which en-v ables the dispensing with the full address at the beginning of the letter, yet assures a perfect postal address on the envelop, and thereby providing positivele 'al proof as to the fact and date of mailing the letter. It is also obvious that the said letter-sheet may be reinforced with advertising or extra pages,- which may'be united therewith with an adhesive .or otherwise.

This combination form, and envelop, process or description, and it may be used in a letter-sheet Copies of this is adapted for matter of any patent ma; be obtained for five cents each, by addressing the .Washington, D. (3.,

for bills, statements, invoices, price-lists, circulars, announcements, invitations, souvenirpost-cards, and for mailing photographs, catalogues or the like, unsealed; and it is to be understood that I do not wish to limit myself to size nor to the number of folding sections herein shown, as it is obvious that a greater or less number may be employed.

1 am aware that changes in the form, and details of construction may be made without departing from the general spirit or sacriicing the advantagesof my invention, and I, therefore reserve the right to make all such changesas fairly fall Within the scope of my invention.

What I claim as my invention is:

The combination and arrangement, in a letter-sheetand envelop, having a plurality of folding sections, one of the sections havcombined end and sideflap provided with row of perforations and an adhesive coating extended along limited inner surface areas; said sections being indented. at intervals, to fold said combined flap inwardly, so as to permanently unite the inner faces ofsaid end flaps, thereby providing an envelop having one side and-end open, to-fold the adjacent sections in or out, for the purpose as specified. f

1n testimony whereof I aliix myfsignature in presence of two witnesses.
